Research on inequality in America shows evidence of a growing social and economic divide between college graduates and people without college degrees. This article examines whether disparities in health between education groups have also recently increased. Pooled cross-sectional regression analyses of data from the National Health Interview Survey (NHIS) show that educational disparities in self-reported health status increased from 1982 to 2004 among older adults but held relatively steady or narrowed among younger adults. Sensitivity analyses show that the trends do not totally or primarily reflect change in the demographic composition of education groups. The trend of increasing disparities among older adults might reflect large and growing educational disparities in economic resources, health-promoting behaviors, or the use of health services and medical technology.
